An early codepoint request means the numbers are “reserved” and when the RFC gets published, they are formally assigned. This is often done for interop testing while the drafts are being written.  Something could change, but it is unlikely.  Sometimes people don’t care and they can wait until the RFC is published for the formal numbers.

So in this case, asking for “early assignment” is the thing to do.

TBH, I don’t know the difference between an early assignment and a late one (And how will it affect the final publication).

But from the implementation point of view, I think the earlier the better. Since lots of companies/organizations in China are waiting for the IANA code-points then they can implement this in their services and products.

This can definitely bring TLSv1.3 online and can make their business complied to the SCA’s requirements at the same time. Would this make a bit of sense I think...

   Hi there,

   A new draft has submitted by me yesterday:

   It describes how new SM cipher suites are used in TLS1.3. There are several code points we would like to request IANA to assign. An IANA consideration section has been included in this draft. I list the detail as follow as well.
   There are 4 TBD values in this draft:

   CipherSuite TLS_SM4_GCM_SM3 = { TBD1, TBD1 };
   CipherSuite TLS_SM4_CCM_SM3 = { TBD2, TBD2 };

   SignatureScheme sm2sig_sm3 = { TBD3 };

   NamedGroup curveSM2 = { TBD4 };

   Note: typos found in original draft, for TBD4 should be in registry “TLS Supported Groups” instead of “TLS HashAlgorithm”. Will fix this in next version of the draft.

   Please review this request, thanks.
